Toxic Or Not Image Map


By the end of this lesson the student should be able to:

  • Identify common indoor air-borne illnesses and contaminants
  • Identify common outdoor air-borne illnesses and contaminants
  • Identify common air-borne illnesses and contaminants of special environments

Lesson Description

The focus of this lesson is the respiratory system; the diseases and contaminants whose main route of entry into the body is through the air we breathe.   Naturally, most of the problems discussed in this lesson are environment-dependant.   Sometimes air-borne environmental hazards cannot be avoided.  Being aware of these hazards is a part of good citizenship because most of these problems can only be dealt with by an informed society working in unison.


There is a pre-test and a post-test for each lesson which must be printed before they are administered. Click here for the key to both tests.

Activities and Assignments

After students have read the lesson, have them work individually or in small groups on the "Slime Sleuths at Toxic Island" activity.   The activity is a mystery game where students will be asked to find out what toxic substance made the patient sick and the source of the substance.  Reading time for each lesson will vary, however, each "Slime Sleuth" activity should not take more than 20 minutes.  There is a different "Slime Sleuth" activity for each lesson, however, to encourage problem solving, the problem presented in the activity may or may not be related to the information in the lesson.  Each computer used for the lesson activity will need an Authorware web player plug-in.
